Patent JP-H09147772-A (JP)
Title: Ion generator and semiconductor manufacturing device using the same
Inventor: TAIRA KENJI
IPC: C23C14/32
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To allow devices to prolong their lives by having a positive-potential chamber, a negative-potential filament, and a filament cover having a number of pores, which is provided around and at a predetermined distance from the filament. SOLUTION: A current is passed through a filament 11 to produce a magnetic field to produce thermoelectrons, which are collided with gas molecules to cause the release of ions, thus producing (+) ions 1. A part of the ions 1 are located between the filament 11 and a filament cover 15, while some of them are allowed to pass through pores H and located between the cover 15 and an arc chamber 10, i.e., outside the cover 15. Because the ions 1 have a positive charge, they repel the chamber 10 that is of positive potential, and tend to migrate toward the filament 11 that is of negative potential. Most of the ions 1 outside the cover 5, however, are blocked by the cover 15 and cannot reach the filament 11. Thus sputtering is avoided, and the rate of wear slows down.

Title: Electric hot-water heater
Inventor: SHIMADA KAZUYUKI
IPC: A47J27/21
Filed: 1987-12-01
Abstract: PURPOSE: To provide an equipment which is safe and easy to use by surely detecting an abnormality when water reaches a dangerous water level which is above a full water level and stopping the heating by a heating element and informing the user of the danger. CONSTITUTION: A cover of a pot is provided with a cover switch 12 to turn on and off when the cover opens and closes. And, a water level pipe is provided with an optical detector 21 to detect a dangerous water level above a high water level. The water level detector 21 works only just after AC power is applied or the cover is closed. When water reaches the dangerous water level, a controlling means 20 turns off a controlling element 29 which controls the energization of electricity to a heating elemnt 32 until water comes below the dangerous water level. When water is below the dangerous water level, on the other hand, the controlling means 20 turns on the controlling element 29.  As a result, even if the heating element is not heated when water is poured into the pot, a priming detection is surely conducted and therefore there is no fear that water boils over and the user gets burnt and the equipment is safe and easy to use.

Title: Video noise reduction circuit
Inventor: YOSHIDA MASAHIRO
IPC: H04N5/21
Filed: 1989-11-22
Abstract: PURPOSE:To realize prescribed noise reduction sufficiently without unsharpening leading and trailing of a video signal by turning off the noise reduction operation for the leading and trailing period of the video signal. CONSTITUTION:A video noise reduction circuit has a noise detection circuit 2, an inverting circuit 3, an adder circuit 4, an integration circuit 6, a subtraction circuit 7 and a switch circuit 8 and detects the leading and trailing period of the video signal to turn off the noise reduction operation for the detection period.

Filed: 1991-09-07
Abstract: PURPOSE:To display the momently changing steering angle of the front wheels of an automobile while an internal dial plate stands still by providing a stilling weight below the casing of a reduction gear the input side of which is supported by a shaft fixed to a central shaft on the bottom of the case of the title meter. CONSTITUTION:The case 1 of this meter is stuck to the center of the steering wheel of an automobile. At the time of sticking the case 1, the case 1 is fitted or stuck to the center of the steering wheel by aligning the neutral position of the meter with the neutral position of the steering angle of the steering wheel. When the steering wheel is then turned, the case 1 turns together with the shaft 2 of the wheel, but the casing of a reduction gear 3 and a dial plate 6 fixed to the front face of a stilling weight 4 remain standstills, because the weight 4 is incorporated in the case 1. A pointer 5 moves in proportion to the movement of the steering wheel in a reduced state. Since the steering angle of the front wheels of the automobile also moves in an interlocking way with the movement of the steering wheel, the pointer 5 functions as the pointer of the steering angle meter of the automobile.

Title: Repeater for communication system
Inventor: OKUBO MASAO
IPC: H04L29/12
Filed: 1990-11-14
Abstract: PURPOSE:To shorten the communication time of a text when it passes through a repeater by outputting one byte data whenever the input of one byte data completes. CONSTITUTION:An input means 11 inputting serial data from a transmission-side, a one byte storage means 12 storing one byte data whenever the input means 11 inputs one byte data and an output means 13 outputting one byte data stored in the one byte storage means 12 to a reception-side immediately after the storage of one byte data into the one byte storage means 12 completes are provided. Whenever the input of one byte data completes, one byte data is outputted. Thus, the communication time of the text becomes longer by the communication time of one byte compared to a case where communication is assumed to directly be executed from the transmission-side to the reception- side without passing through the repeater.

Abstract: PURPOSE:To measure the speed of a light pervious object with good accuracy in a non-contact state, by respectively arranging polarizing plates on the light path reaching the light pervious object from a light source and on the light path reaching a space filter from the light pervious object. CONSTITUTION:The first polarizing plate 8 is arranged on the light path reaching a light pervious object from an illumination light source 2 and the second polarizing plate 9 is arranged on the light path reaching a speed detector 6 from the light pervious object 1. By this constitution, when the light pervious object 1 has optical anisotropy, the directions of the polarizing axes of the aforementioned polarizing plates 8, 9 are adjusted to illuminate the light pervious object 1 by white light from the illumination light source 2. Whereupon, a colored pattern corresponding to the double refractivity distribution or thickness distribution of the object 1 appears on the object 1 by the double refraction phenomenon of the object 1. Since this pattern is observed so as to move at a speed V in the direction shown by an arrow A with the movement of the object 1, the quantity of the light received by a light detector 5 through a space filter 4 changes corresponding to the running speed of the colored pattern and the speed of the light pervious object 1 can be stably measured.
